I found old domino pieces from a game, thrown by somebody, and an easy DIY Domino clock idea came to life.

Step 1: The Idea

Like I said in the intro of this instructable, my girlfriend and I found old domino pieces from a game thrown down by somebody and I said to her: " Why don't we pick them and create a DIY Domino clock ?!"

We pickup the pieces, wash them and thought what tools we will need to accomplish it. The next steps will tell you in details how did we do it.

My girlfriend do all the steps coordinated by me, because she was very enthusiastic about the creation part and less for the document it and video making.

Step 2: Gather the Needed Tools

Parts needed (in my case):

- Domino pieces

- Clock mechanism (with nut, washer and hour, minutes and seconds hands - AA battery)

Dimension: 55mm/55mm/H 15mm

Central shaft thickness: 7.5mm

Width of central shaft: 11mm, threaded 5mm

For panel of max thickness: 3mm,

- Cardboard or in my case an image panel (30cmx40cm)

- ruler

- pencil

- something straight to draw the center line

- glue pistol

- a battery drill with 6mm bit (a little smaller than the clock in my case)

- small pliers

Step 3: Find the Center of the Board

In order to find the center of the board I marked with the pencil a short line about in the middle from a right top corner to left bottom corner and vice-versa (left top corner to right bottom corner)

Step 4: Glue the First Domino Pieces

Measure the width and height of the board with the ruler, in my case it has 30cm x 40cm, and mark the half of them (15cm x 20 cm ) on each side.

After that, take the glue gun and put 4 "beans" in each corner of the domino piece (numbers: 12, 3, 6, and 9) and stick it to the panel.

Step 5: Drill the Center of the Board and Mount the Clock

With the 6mm bit I drilled the center and enlarged the hole until the clock assembly fit in with a little bit of force. (the clock it self has 7,5mm thickness so also a 7mm bit can be use and then enlarge easy the remaining 0.5 mm.

With the small pliers I tighten the clock nut to fix the mechanism and then ,by hand, i started to mount the hour line, minute and then seconds by pushing them.
